Leaving a breadcrumb for people who follow this path… I’m focusing on tablet apps and newer devices, so from the beginning of CriminalIntent, I’ve set my minimum API level to 14, and did not include Android.Support.v4. That worked fine, until I needed a ViewPager for this chapter. There is no ViewPager in the main Android libraries! Introducing the v4 support library at this point caused cascading incompatibilities, so I started looking for ways to implement the functionality without ViewPager. This was not a good idea for a newbie Android dev.
However, there is a newer support library, Android.Support.v13. You still need the v4 library for ViewPager, but v13 makes it work smoothly with the main Android libraries for activities, fragments, adapters, etc. So this appears to be the answer.
BTW, excellent book so far! I really appreciate the focus on immersing in code from page 1. Because I’m interested in cross-platform mobile app development, I’m using Xamarin.Android and C# rather than Eclipse and Java, but so far, so good.
